(a) A heart or a black card
(b) A heart or a jack
(c) A heart and the ace of clubs
(d) A 9 or a jack
(e) The 9 of hearts or a jack
Answer:
3/44/137/262/135.52Step-by-step explanation:
(a)
Probability (A heart or a black card) = 13 + 26 / 52Probability (A heart or a black card) = 39/52Probability (A heart or a black card) = 3/4(b)
Probability (A heart or a jack) = 13 + 3 / 52Probability (A heart or a jack) = 16/52Probability (A heart or a jack) = 4/13(c)
Probability (A heart and the ace of clubs) = 13 + 1 / 52Probability (A heart and the ace of clubs) = 14/52Probability (A heart and the ace of clubs) = 7/26(d)
Probability (A 9 or a jack) = 4 + 4 / 52Probability (A 9 or a jack) = 8/52Probability (A 9 or a jack) = 2/13(e)
Probability (The 9 of hearts or a jack) = 1 + 4 / 52Probability (The 9 of hearts or a jack) = 5/52What is the area of this shape?
The area of the figure presented in the image, which is formed by one right triangle and three rectangles is equal to an amount of 157 square kilometers.
How to determine the area of a compound shape
In this question we understand that the area of the compound shape is the sum of the area of small rectangles and triangles:
[tex]A = \sum \limits^{n}_{i = 1} A_{i}[/tex] (1)
Now we proceed to calculate the area of the compound shape:
A = 0.5 · (4 km) · (3 km) + (10 km) · (2 km) + (17 km) · (7 km) + (2 km) · (6 km)
A = 157 km²

Given JAM and segment PB such that PB JM, what is the missing justification in the proof that JP/PA = MB/BA
Answer: AA similarity posulate
Step-by-step explanation:
In ΔAJM and ΔAPB,
∠PAB = ∠JAM,
Also, since PB || JM, the corresponding angles formed by these two parallel lines with the line AJ are equal i.e.
∠AJM = ∠APB
So, using the AA similarity postulate, we can say that ΔAJM is similar to ΔAPB

Ten blackberry plants start growing in my yard. Absent constraint, blackberries will spread by 200% a month. My yard can only sustain about 50 plants. Using the logistic growth model, a. Write a recursive formula for the number of blackberry plants in my yard b. Calculate the number of plants after 1, 2, and 3 months
The recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10
The recursive functionThe given parameters are:
Initial = 10Maximum = 50Growth rate = 200%The number of plants in month n is calculated using:
Tn = Tn-1 * (1 + 200%)
This gives
Tn = 3Tn-1
Hence, the recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10
The number of plants after 1, 2, and 3 monthsThis means that n = 1, 2, 3
When n = 1, we have:
T1 = 3To = 3 * 10 = 30
When n = 2, we have:
T2 = 3T1 = 3 * 30 = 90
90 is greater than the maximum number of plant the backyard can contain
Hence, the number of plants after 1 month is 30 and the plants in the backyard would exceed 50 plants before the end of the 2 months

What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?
Answer:
The distance is 1.41 to nearest hundredth.
Step-by-step explanation:
The line y = x + 3 passes through the point (0, 3) on the yaxis.
Find the perpendicular line passing through this point:
y - 3 = -1(x + 0)
y = -x + 3
Now find the point where this line intersects the line y = x + 1:
y = -x + 3
y = x + 1
-x + 3 = x + 1
3 -1 = x + x
2x = 2
x = 1
and y = 2
So this point is (1, 2)
We require the distance between this point and (0, 3)

Given = 3(x - 4) + 5x = 9x - 36
Step 1 = 3x - 12 + 5x = 9x - 36
Step 2 = 3x + 5x - 12 = 9x - 36
Step 3 =› 8x - 12 = 9x - 36
Step 4 => 8x - 8x - 12 = 9x - 8x - 36
Step 5 = 0 - 12 = x - 36
Step 6 = -12 = x - 36
